JOHN ZIMERMANN, OF PHILADELPHIA, PENNSYLVANIA.

COP-WINDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 585,247, dated June 29, 1897.

Application filed December 18, 1896. Serial No. 616,167. (No model.)

To all] whom it nut cancel-1t.-

Be it known that I, JOHN ZIMERMANN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Oop Winding Machines, of which the following is a specification.

My invention relates to machines for winding yarn into shuttle-cops, which yarn is used as weft in weaving; and it relates, first, to a mechanism for operating the traverse yarnguide, which guide lays the yarn and builds up the cop; second, to a stop mechanism which will shift the spindle-driving belt and stop the motion of the cop-Winding spindle when the yarn runs out, breaks, or a full cop is wound.

The invention consists, first, in combining with each spindle of the machine a traverse mechanism driven and operated by a positive motion from the spindle with which it coopcrates; second, in the combination of a beltshifting mechanism as will shift the spindledriving belt from a tight to a loose pulley and stop the cop-winding spindle When 'the yarn runs out, breaks, or a full cop is made.

It is well known to weavers and others having charge of cop winding machines that where one traverse mechanism is used to lay the yarn on a series of spindles if one of the spindle-driving belts be slack that spindle will wind a bad cop and a bad cop will make waste. Therefore I have devised and invented a mechanism in which I have combined a traverse with each'spindle of the machine and which traverse is driven each by its own spindle, as illustrated in the accompanying drawings, in Which- Figure 1 is a side elevation view of a copspindle, stop-motion, and traverse-guide c011- structed according to my invention; Fig. 2, a front view of Fig. 1; Fig. 3, a back view of Fig. 1. Figs. 4and 5 are views of the traversecam. Figs. 6 and 7 are views of the bush for the loose pulley. Figs. 8 and 9 are views of the spindle-driving sleeve.

Similar numerals of reference refer to like parts in all figures.

The construction of my invention is as follows:

Referrin g to the drawings, 1 represents the cup, in which is formed the cop, and 8 the spin dle-driving sleeve, which sleeve has a square hole through the center its entire length. This sleeve 8 is mounted loose in the frame 1 and held in place by caps 17 and 18. At 8 is fixed a pinion-wheel 20. Below the cap 17 is fixed the fast driving-pulley 5. Below this pulley 5 is placed the bush 7. In this bush is a steady-pin 7. This steady-pin fits in a hole drilled in frame 1. (See 7, dotted lines, Fig. 3.) On the bush 7 is fitted the loose pulley 6.

9 represents the traverse-cam fixed to spurwheel 9. This wheel and cam are mounted on a stud 9", which stud is fixed to frame 1. (See Fig. 3.) I

3, Figs. 1 and 3, represents the belt-shifter. This belt-shifter is pivoted at top by shaft 3 and at bottom by shaft 3. To this lower shaft 3 is fixed the belt-guide 4. (See Figs. 1 and 3.) This belt-shifter has a handle 21, and when lifted to put the belt on the fast pulley 5 the belt-shifter 3 is supported 011 the catch 22. (See Fig. 1.)

12, .Fig. 1, represents a pivoted tension-1e ver common'on cop-Winding machines. At 14 the yarn to be wound runs under this end of the lever and holdsit up when running to the cop. From the hub of the lever 12 is a Wire arm 13. (See Fig. 1.)

23 represents the yarn-guide wire. At the top it guides the yarn into the cone-cup 2 to form the cop. At the bottom it rests on the cam 9, and when the cam is rotated it freely rises and falls in the guides 24 and 25, Fig. 2. The drag of the yarn keeps it up against the cone-cup 2, it being free, so as to turn in the guides 24 and 25 as it rises and falls.

At the bottom of spindle 2 is a collar 10. At the bottom of the belt-shifter 3 is fixed an arm 11. (See Fig. 1.) k

The operation of myinvention is as follows: When the driving-belt is on the fast pulley 5, the belt-shifter 3 will rest on the catch 22, Fig. 1. The pulley 5 drives the sleeve 8,

which in turn drives the spindle 2 and cam 9.

The yarn as it windson the spindle is shaped by the cone-cup 2 and causes the spindle to raise it, being adapted to slide free in the sleeve 8. When a cop of the proper length has been wound, the collar 10 on the bottom of the spindle will revolve against the arm 11 and swivel the shaft 3, so as to turn the belt-shifter off from the catch 22, drop the belt-shifter, shift the driving-belt from pulley to pulley 6, and stop the spindle. If the yarn breaks or runs out the tension-arm 12 drops. This causes the arm 13 to push the belt-shifter off the catch 22, and the spindle 2 will be stopped before the yarn end has been run into the cone-cup 2. If the yarn thread be tied and placed under the arm 12 at 14 and the belt-shifter be raised and placed on catch 22, the spindle will run and wind until stopped bythe collar or arm 13, as before described.

Having as above fully described the construction and operation of my invention, what 1. In a Weft cop-winding machine, the combination of the following elements; a conecup, a vertical sliding spindle, a fast and a loose pulley, through which said spindle slides, a traverse-cam, spur-gears connecting it and the pulleys, and a yarn-guide movable by said traverse-cam and bearing against the cone-cup, whereby the yarn-guide is given both a vertical and horizontal movement, as shown and described.

2. In a weft cop-winding machine, the combination of the following elements; a fast and loose pulley, a vertical sliding spindle, passing through the pulleys, a belt-shifter, a retaining-catch, an arm 11, on said beltshifter, and a collar 10, on the lower end of the vertical spindle, effecting the disengagement of the catch and shifter, for stopping the spindle when a full cop has been wound,

substantially as shown and described.
